Zlenko I. Agroecological factors of the microbioconenoses in the initial stages of the biological development of the reclaimed lands (for example of Nikopol manganese mining basin)

Investigation develoded to the factors of the microbioconenoses forming in the initial stages of the biological occupation of the reclaimed lands, formed of Pleistocene-Miocene potentially fertile overburden rocks (loess loam, red-brown and gray- green marly clays) without covering their fertile stratum of soil mass. It was established the microbe population composition of the overburden rocks of manganese layer in the places of fundamental bedding. The ways of rocks contamination and microbe group forming tendencies have been analyzed in the heaps with different age. It was selected the stages of rocks settling the peculiarities of the microorganisms number under fields and fruit-berry crops ware studied.
